The biological activity of the majority of substances presented in egg matter is related to their anti-microbial and anti-cancer properties and their immunogenic features as well. Due to the use of new generation of feed additives and techniques of immunisation of hens, the chemical composition and biological features of eggs may be modified and enriched with desired components, like n-3 fatty acids （alpha-linolenic acid （ALA）, docosahexaenoic acid （DHA） phospholipids）, vitamins, microelements. Egg material may also be used for the production of new biopreparations for the prophylaxis of various civilisation diseases, such as heart and cardiovascular diseases, cancers, neurogenerative disorders, metabolic bone diseases etc.. New progress in egg science allowed to discover new bioactive substances, like monomeric and dimeric cystatin and yolkin. It is necessary to develop efficient methods of isolation of biologically active substances contained in eggs, which would make it possible to produce new generation of diet supplements and biomedical products. It seems that new generation of eggs could be the best source for production of natural, high value nutraceutical supplements of diet, and also biomedical and biocosmetic preparations.展开更多

Further understanding of these proteins and their mechanisms in egg defence could lead to the development of novel neutraceuticals for human health, additives to animal feed for healthy flocks, or enhanced eggs for human consumption.展开更多
